easily be bounded with the addition of the diodes shown without degrading the current sensing accuracy. This bounding technique

can be used in any of the MC33341 applications where high peak currents are anticipated.

NOTE: Multiple outputs can be controlled by summing the error signal into a common optoisolator. The converter output with the largest

voltage or current error will dominate control of the feedback loop.
